4a) Calculate alpha for each portfolio. Assume that gamma equals 1% and the risk-free rate equals 2%. Portfolio A Portfolio Return 17.2% 14.3% 11.1% 7.6% Market Std Dev 10.0% 10.0% 10.0% 10.0% Portfolio Std Dev 12.0% 14.0% 7.0% 8.0% Portfolio Correlation w/ Market 0.720 0.300 0.600 0.030 Market Return 12.0% 12.0% 12.0% 12.0% B D 4b). Now assume that gamma for each portfolio was 0%. How does this alter Beta and Alpha in part a)
